What does the survey comprise?
Purpose
The HPI measures the price development of dwellings purchased by households. The dwelling must be located on Dutch territory and sold to a private person.
Target population
Sold dwellings, both newly built and existing owner-occupied dwellings
Statistical unit
Owner-occupied dwellings, newly built and existing owner-occupied dwellings
Date/year survey started
The HPI is a weighted aggregate of the price index for newly built dwellings (PND) and the price index for existing dwellings (PED). The PED is calculated on a monthly basis and available from 1995. The PND is calculated on a quarterly basis and available from 2015. The HPI is therefore calculated on a quarterly basis and starting in 2015. The longer series for the PED before 2015 is published in the table Existing own homes; purchase price indices by type of dwelling 2020=100.
Frequency
Quarterly
Publication strategy
The price index figures of the HPI and PND remain provisional for one quarter. The number of sold dwellings are provisional for four quarters. All figures of the PED are definite. Approximately 3 months after the reporting month, the figures will be published.
How is the survey conducted?
Survey type
The HPI is a weighted aggregate of the PND and PED. The weights represent the annual total value of purchase prices of newly built dwellings and existing dwellings. It is calculated by summing up the selling prices of all dwellings sold in a year. Each year new weights are calculated. A detailed description of the method can be found in the document ‘Survey method House Price Index’.
The PND is based on a survey amongst a sample of developers who sell newly built dwellings. The number of sold dwellings and the total value purchase prices associated with the PND are based on a complete registration of housing transactions at the Land Registry. A detailed description of the method can be found in this document. (only in dutch)
The PED is based on a complete registration of housing transactions at the Land Registry. A detailed description of the method can be found in the document ‘Survey method Price index existing dwellings’.
Survey method
The data collection for the PND takes place with the help of questionnaires. The observations for the number of sold dwellings for newly built dwellings and for the PED take place with the help of data from the Land Registry.
Respondents
The Land Registry and companies (selling developers of newly built dwellings).
Sample size
For the PND approximately 300 companies are observed each quarter.
